Details
As written in the advisory (Markdown source, shown as plain text).
**Overview**
Session cookies of applications using the Auth0-PHP SDK configured with CookieStore have authentication tags that can be brute forced, which may result in unauthorized access.
**Am I Affected?**
You are affected by this vulnerability if you meet the following pre-conditions:
1. Applications using the Auth0-PHP SDK, or the following SDKs that rely on the Auth0-PHP SDK:
a. Auth0/symfony,
b. Auth0/laravel-auth0,
c. Auth0/wordpress,
2. Session storage configured with CookieStore.
**Fix**
Upgrade Auth0/Auth0-PHP to v8.14.0. As an additional precautionary measure, we recommend rotating your cookie encryption keys. Note that once updated, any previous session cookies will be rejected.
